More information on recent exoplanetary discoveries can be found on NASA's Exoplanet Exploration News.

Methods of Detecting Exoplanets

One of the primary methods of detecting exoplanets is the transit method. This technique involves monitoring a star for a regular dimming of its light, which indicates that a planet is passing in front of the star from our viewpoint. The transit method has been particularly effective in discovering a vast number of exoplanets, as it allows astronomers to measure the planet's size and orbit. NASA's Transiting Exoplanet Survey Satellite (TESS) is a leading mission in utilizing the transit method, continuously scanning the skies for potential new worlds [source].

Another method used to discover exoplanets is the radial velocity or Doppler method. This technique detects wobbles in a star's motion caused by the gravitational pull of an orbiting planet. By observing the changes in the star's spectral lines, astronomers can infer the presence of a planet, as well as determine its mass and the shape of its orbit. The radial velocity method is especially valuable for finding large planets situated close to their host stars [source].

The direct imaging approach allows scientists to capture actual images of exoplanets by blocking out the light from the host stars using advanced instruments like coronagraphs. This method is challenging but essential for studying planets that are located at a greater distance from their stars. Direct imaging provides valuable information about the planet’s atmosphere and gives a clear view of its potential moons or rings, enhancing our understanding of exoplanetary systems [source].

Gravitational microlensing is another exciting method of detecting exoplanets, relying on the bending of light from a distant star caused by the gravitational field of a closer star-planet system. This phenomenon allows astronomers to spot planets that are otherwise too faint or distant. Microlensing is unique among planet detection methods because it can reveal information about exoplanets in distant galaxies as well as those in the Milky Way [source].

The astrometry method, long anticipated but still emerging in its capabilities, involves measuring the precise movements of stars in the sky. A nearby star's position shifts as it is subtly tugged by an orbiting planet, and astrometry aims to detect these movements to determine a planet's presence and characteristics. While technically demanding, advancements in astrometric technologies continue to promise new discoveries of exoplanets, particularly those orbiting farther from their host stars [source].
